To all whom it may concern;

Be it known that I, HENRI G. LEVY a citizen of the United States, residing at en Francisco, in the county of San Francisco and State of California, have invented a new and useful Tire Look, of which the -follow-' ing is a specification.

This invention relates particularly to means for locking vehicle tires onto vehicle wheels or onto t1re racks or other mountings.

Among the objects of the.v invention are to prevent the'theft, particularly of pneumatic tires, from automobile. wheels or from their carrying racks, and to provide such a look as will be adaptable to the present-construction and arrangement of pneumatic tires on permanent or demountable rims, to prevent the theft thereof from the vehicle wheels or the'spare tires carried on suitable carriers.

With the above objects in view the inven tion consists generally of a novel combination of elements subsisting among the tire,

its mounting which is provided with means for holding the tire, a stem such as the valve stem which projects through said mounting and has means at its inner end for co-operation with the mounting to secure the tire,

and the locking element which is fitted to the stem and co-operates therewith and with the mounting to provide a positive lock which can not be manipulated b enunauthorized person and which wi prevent the theft of the tire from its mountlng under any condition of inflation or deflation; the invention also consists in novel details of structure and arrangement appurtenantto such. combination.

', ,In this specification and; the annexed drawings, the invention is illustrated in the form considered to he the best, but it is to be understood that the invention is not limited to such form, because it ma be em-- bodied in' other forms, and it is a so to be understood that in and byuthe'claims following the description, it'is desired to cover the invention in'whatever form it maybe embodied. v p In the accompanying one sheet of drawin s: 1

bow engaging a tire valve shown incross section.

In detail tlie construction illustrated in.

the drawings includes,referring. to Fig. 1',

the tire casing I mounted on the conventional rim 2 which is fixed, or demountably attached, tothe felly 3,015 the "vehicle rim" and which includes flanges 2 'for holding the tire. The tli'e casing has the usual inner air tube 4, provided withthevalve stem 5 fixed therein and extending through the'rim H 2 and the felly 3% through which it protrudes; i

This valve isthr ade'd throughout its length to receive the jam nut 6, which'holds the spreader 7 and the washer 8 and the wall-of the inner tube 4, in compressed assembly 7 against the head 9. of the valve stem, ..t hespreader co-operating with the r m and 1ts flanges 2 to secure the tire to the rim, The

running nut 10 provided with an internal compression washer '(not shown), .111 the usual manner, is threaded on the valve stem j and bears against the felly to coventhehole therethrough for the passingof the. valve stem. Thus far thB COIISfiI'UCtIOIII S conventional and is encountered with various modifications in this art.

The locking device as 1, 2. and 3, comprises a lock 11 preferably of the pad lock type, having the how 12 with the extensions 13 and 14 extending into the pad lock' to be .engagedfby the locking bolt controlled by the removable key 15. The opening 16 between the interior of the bow'and the end of the padlock'is of a contour to fit snugly the perimeter of-the valveillustrated in Figs.

stem which.;c onsists of a circle having flat-- tened sides 17 and 18 to' engage the flat side 'of the valve stem, extensions 19 and20- of the circle being threadedto Iengagethe thread 108 on'the valve stem to pre'ventthe pad lockfrom being moved longitudinally on the valve stem. The lock 11 and the how 12 are each provided with the semicircular lugs 21-22,.which combined form a true circle having an annular groove therein to engage the annular flange 23 formed on the dust cap 24, which is in the form of a. tubular thimble entirely inclosing the end of the valve stem 5. The valve stem is provided with an'interior spring operated check valve (not shown) to hold the air pressure pumped into the inner tube 4. The end of the valve stem being reduced and threaded to receive the valve cap 25provide d with a gasket to,

seal the end of the valve stem, in the usual manner.

This inventionoperates substantially as follows: The padlock in the open position, as shown in Fig; 3, is inserted over the protruding end of the valve stem to a position at rest on top of the nut 10, the dust.

cap 24, the neck 26 of which need not be threaded, clears the threads on the valve stem and is inserted over the end of the valve stem inclosing the valve cap. The padlock is then closed, and its parts locked ,together to co-operate with the stem 5 and the tire mountin in positively locking the 'tire to the mountlng and, in the embodiment .disclosed, to en age the flange 23 on the the valve stem and the tire mounting, positively and securely to lock the tire 1 on the felly 3 and to prevent its removal until the removal of the padlock 11. The particular reason for locking the dust cap 24 in position is to prevent. the deflation of the tire by the removal of the valve cap 25 and the unseating of the valve in which manner the air could be removed noiselessly and without causing suspicion. On theother hand, if the valve stem were broken off while the tire was inflated, the sudden rush of air from the valve would cause a whistling noise giving warnin that the tire was being tampered with, whlch in itself would act as'a deterrent to the ordinarypetty larcenist. It is obvious that the application of this lock in no wa interferes with the normal functioning o the parts to which it is attached.

In Figs. 4 and 5 is illustrated a modification of the lock, in which the reduced neck 27 is'threaded to engage the thread on the valve stem 5, as is now common practice.

. The end of the dust cap is notched as at 28 to engage the lug 29 formed on the lock 30. This lock 30 is similar in "every way to the lockl l except that" it is unnecessary to th ead the b 3l an the and of the lock as at 19 and 20 shown Fig. 2, but the contour of the bow and the end of the padlock are made to snugly engage the perimeter of the valve stem. The lug 29 engaging the notch 28 prevents the unscrewing of the dust cap because of the non-rotatable engagement of the padlock with the valve stem. The how 31 is locked by the removable key 32. The bow may be of the sliding type illustrated in Figs. 2 and 3, or may be pivoted as at 33, to swing out ofengagement with the valve stem. The particular form of the lock is not germane to this invention and may be varied to suit circumstances or the taste of the'producer. k

In Fig. 4 the annulus 34 of the tire rack is indicated to show the application of the lock to tires carried on the rack, inflated ready for application to the vehicle wheel. The mode of operation of the lock in either instance is the same, except that the lock 30 lies against the annulus 34 instead of against the felly of the wheel or the nut 10.

Having thus described this invention,

what I claim and desire to secure by Lette'rs Patent is: g 1. In combination, an inflatable vehicle tire having an infiating valve provided with a dust cap, a felly through which said valve projects, and a lock adapted to bear against the felly and to engage the dust cap and comprising two complemental members having semicircular portions to forma circular opening adapted to receive the valve below the dust cap thereof, said opening having at least one flattened surface to engage a corresponding surface on thevalve, at least one of the members having means engage. able with the lower portion ofthe dust cap to prevent an axial movement thereof relative to the valve, and a key controlled locking means for securing said members in and! releasing them from eflective locking position.
